Specifically, since the shell side of the shell 1 is divided into the upper and lower parts by the shell side partition plate 4, when molten salt flows in from the molten salt inlet 5, the molten salt flows from the right side to the left side along the pipe wall of the electric heating pipe 3 positioned below the shell side partition plate 4, and then flows from the left side to the right side along the pipe wall of the electric heating pipe 3 positioned above the shell side partition plate 4, and in the flowing process, the molten salt is heated by heat generated by the resistance wire in the electric heating pipe 3.

The application method of the fused salt storage tank electric heating device for enhancing heat transfer comprises the following steps: when the temperature of the molten salt storage tank 11 is reduced, low-temperature molten salt in the molten salt storage tank 11 flows through the molten salt regulating valve 9 under the action of the molten salt pump 8, and enters the molten salt storage tank electric heating device from the molten salt inlet 5; molten salt firstly flows from the right side to the left side along the pipe wall of the electric heating pipe 3 positioned below the shell-side partition plate 4, then flows from the left side to the right side along the pipe wall of the electric heating pipe 3 positioned above the shell-side partition plate 4, exchanges heat with the electric heating pipe 3, and flows out of the molten salt outlet 6 after heat exchange into the molten salt storage tank 11.
Specifically, when the temperature of the molten salt storage tank 11 is reduced, the molten salt storage tank electric heating device, the molten salt pump 8 and the molten salt regulating valve 9 are started, and low-temperature molten salt in the molten salt storage tank 11 is pumped out under the action of the molten salt pump 8 and then enters the molten salt storage tank electric heating device from the molten salt inlet 5. The molten salt flows from bottom to top on the whole shell side, the molten salt on the shell side flows from right side to left side along the pipe wall of the electric heating pipe 3 positioned below the shell side partition plate 4, then flows from left side to right side along the pipe wall of the electric heating pipe 3 positioned above the shell side partition plate 4, exchanges heat with the electric heating pipe 3, and the molten salt after heat exchange flows back to the molten salt storage tank 11 from the molten salt outlet 6.

In the process of heating the molten salt, the opening of the molten salt regulating valve 9 is regulated through temperature feedback of a temperature measuring element 10 arranged on an outlet pipeline 13 so as to control the flow rate of the molten salt flowing through a pipeline of the molten salt inlet 5, and when the temperature measured by the temperature measuring element 10 is higher, the opening of the molten salt regulating valve 9 is increased, and the flow rate of the molten salt in an inlet pipeline 12 is increased; when the temperature measured by the temperature measuring element 10 is lower, the opening degree of the molten salt regulating valve 9 is reduced, and the flow rate of the molten salt in the inlet pipeline 12 is reduced.
According to the fused salt storage tank electric heating device, fused salt is adopted as an intermediate heat transfer medium, and a heat transfer mode is replaced by forced convection, so that compared with natural convection of air, the internal heat transfer efficiency of the electric heater is improved, and the overtemperature jump stop risk of the electric heating pipe 3 is reduced; on the other hand, the rib 2 is arranged outside the shell 1, so that the internal circulation of the fused salt storage tank 11 is increased, the contact temperature difference between the shell 1 and the tank wall of the fused salt storage tank 11 is reduced, the thermal stress of the contact surface between the electric heating device body and the fused salt storage tank 11 is improved, and the risk of leakage of the fused salt storage tank 11 is reduced.
